New York -- Best Buy’s chief marketing officer, Barry Judge, has resigned. His resignation follows the departure last month of chief executive Brian Dunn.

Judge is “leaving the company to explore the next chapter in his career,” Greg Hitt, a spokesman for Best Buy, said by e-mail, in a Bloomberg report.

Stephen Gillett, a former Starbucks executive who joined Best Buy in March, will take over responsibility for the chain’s marketing efforts, Minnesota Public Radio reported. Gillett was hired to bolster Best Buy's e-commerce efforts as president of Best Buy Digital and Global Business Services.

Best Buy is searching for a new CEO in the wake of Dunn departure. Dunn is currently the subject of a board investigation of his personal conduct.
